Came into Formula 3000 with a blaze of publicity, especially as his sister Paula was in Formula 3 at the time and as well as that Cook was 1996 Formula Renault V6 Champion. Ran his own team, DC Motorsports, but left the sport after a relatively brief spell in F3000. David still lives in Rotherham and previously ran a motorsport parts business and a leasing company, and concentrated his efforts on his nephew Jake and his racing career - Jake raced in Formula Renault in 2013 and 2014.
